    摘要： In a sourceless orientation sensor, the sensor measures the three orientation angles azimuth, elevation and roll in a fixed reference three-dimensional coordinate frame. The sensor utilizes a three-axis magnetic sensor to measure changes in the Earth's magnetic field in order to determine the azimuth and roll (or elevation) angles after the elevation (or roll) angle has been determined by other means. A first embodiment utilizes a separate sensor to measure the elevation (or roll) angle in a fixed reference three-dimensional coordinate frame while a three axis magnetic sensor is used to measure the Earth's magnetic field. The azimuth and the roll (or elevation) angles are then determined from these measurements. A second embodiment utilizes a combination of a three-axis accelerometer to sense the Earth's gravity to measure the absolute elevation and roll angles for slow motions and a two-axis rate sensor to measure the azimuth and elevation velocities in the sensor frame. A direct method employing translation and integration is used to find the azimuth and elevation angles in the fixed reference three-dimensional coordinate frame. The roll angle is then found from the magnetic sensor measurements. Other embodiments are disclosed.

    摘要翻译： 在无源定向传感器中，传感器测量固定参考三维坐标系中的三个方位角方位角，仰角和滚动角。 传感器利用三轴磁传感器来测量地球磁场的变化，以便通过其他方式确定仰角（或滚动角度）后的方位角和倾斜角（或仰角）。 第一实施例利用单独的传感器来测量固定参考三维坐标系中的仰角（或滚动角），同时使用三轴磁传感器来测量地球的磁场。 然后从这些测量中确定方位角和滚动角（或仰角）。 第二实施例利用三轴加速度计的组合来感测地球的重力以测量用于慢速运动的绝对高程和滚动角以及用于测量传感器框架中的方位角和仰角速度的双轴速率传感器。 使用平移和积分的直接方法来找出固定参考三维坐标系中的方位角和仰角。 然后从磁传感器测量中找出滚动角度。 公开了其他实施例。

    摘要： There is disclosed, a desalination apparatus making use of a particles including covalently bonded functionalized magnetic nanoparticles coupled to a complexing agent. For example, the complexing agent may include a crown ether. The particles are optionally used for removing salt from water, for example sea water. The apparatus optionally includes a magnet for magnetic filtering, concentrating and/or removing the particles and/or contaminant (e.g. salt). In some embodiments, the salt is then separated back from the particles using UV light. The remaining unclarified water may be washed out with the contaminant and/or used for salt production and/or disposed of (e.g. dumped back to the sea). Optionally, the particles are regenerated. For example, the regenerated particulars may be reused for further desalination steps (e.g. further salt removal from the clarified water) to clarify new input water.

    摘要： A method of correcting for aberrations in scattering data is described which does not require prior knowledge about the sample microstructure properties or calculations based on the modelling of peak locations. In an example, X-ray scattering apparatus integrates a correction device arranged to automatically calculate and output aberration corrected output X-ray pattern using the aberration Fourier presentation Finst(H,2θ) dependent from the scattering angle 2θ and the Fourier transform of the measured X-ray scattering pattern Fexp(H).
